arm gcc获取并不困难,可以访问arm的官方页面直接下载: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm 下载后一路无脑安装即可,这里就不再赘述。接下来,我们打开MDK,通过菜单project->New uVision Project...新建一个工程: 为了方便,工程文件名不妨就叫gc...
名称LLVM是Low Level Virtual Machine的缩写,尽管名称如此,但是LLVM与传统虚拟机关系不大,它是LLVM项目的全名。 The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name "LLVM" itself...
-O1 Optimize. Optimizing compilation takes somewhat more time, and a lot more memory for a large function. -O2 Optimize even more. GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff. As compared to -O, this option increases both compilation time and the...
常用编译选项gcc and g++分别是gnu的c & c++编译器 gcc/g++在执行编译工作的时候,总共需要4步 1.预处理,生成.i的文件[预处理器cpp] 2.将预处理后的文件不转换成汇编语言,生成文件.s[编译器egcs] 3.有汇编变为…
链接的主要过程包括:地址和空间分配(Address and Storage Allocation),符号决议(Symbol Resolution),重定位(Relocation) 等。 链接分为静态链接和动态链接。 静态链接是指在编译阶段直接把静态库加入到可执行文件中去,这样可执行文件会比较大。 而动态链接则是指链接阶段仅仅只加入一些描述信息,而程序执行时再从系统中...
编译步骤 gcc 与 g++ 区别 gcc 命令的常用选项 编译优化选项 -O 优化 -O1优化 -O2 -O0 -Os -Ofast -Og -Oz -O 选项控制特定的优化 Warnings Reference 编译步骤 gcc 、 g++分别是gnu的c & c++编译器 。实际上,G

彼方唱罢我登场,而后在GCC改进了自己的诊断程序后,又发布了就其性能提升后的文章,标题是“Comparison of Diagnostics between GCC and Clang”,可以看到非常直白和露骨了... 我们可以通过测试Clang 6.0.0、GCC 7.3.0中常见错误,同时通过编译器资源管理器MSVC 2017 19.10.25107来检验谁的性能更好。需要特别说明的...
same variable in different compilation units to the same object, or to a non-tentative definition. This behavior is inconsistent with C++, and on many targets implies a speed and code size penalty on global variable references. It is mainly useful to enable legacy code to link without errors....
